By H. W. Bates, Esq.
In the Transactions of the Entomological Society of London I have
commenced a series of papers on the subject of the insect fauna of
the valley of the Amazons, the result of eleven years' research in that
region. They are Limited at present to the group of Rhopalocerous
or Diurnal Lepidoptera, and, besides a detailed review of the genera
and species, will contain an investigation of the general question of
the natiu'e and relations of the fauna, which that group of insects is
so well calculated to illustrate. I shall not be able, nor will it be
necessary, to treat the whole, or any considerable number, of the insect
families in the same copious way ; it will be sufficient if I give from
time to time, as the materials become completed, shorter essays upon
detached families or smaller groups, communicating any facts that
I may have observed regarding their habits, and describing the new
species. In some groups, even of the favourite order Coleoptera,
this task will be surrounded with difficulties in consequence of no
recent monograph existing embodying in a connected form the
various memoirs on the subject, thus necessitating tedious research
for the already jjublished descriptions in the bewildering maze of
entomological literatiu'e. The object of the present paper is to give
